RAIL-CHAIR.

Specification of Letters Patent.

Patented Mar. 21 .1911.

a citizen of the United States, residing at Sunbury, in the county of Northumberland' and State of Pennsylvania, have invented new and useful Improvements in Hail Chairs, ofwhich the following is a specifica- This invention relates to rail choirs and particularly to that type which are adapted to support the ends of the rails when they meet between ties.

The object of the invention is the provi sion of a rail joint having means to draw the ends of the rails together whereby a tight joint' is toriiied and bumping thereby eliminated.

A further object of the invention is the provision of a joint chair having means for I of the rails and ther heads 4 and bases 5.

Fig. 2 is a similar View with the adjusting plate re moved. of one of the fish plate sect-ions.

at is a horimnt-al section-taken on the line 4-4 of Fig. 1. Fig. 5 a top plan view. Fig. 6

is a transverse sectional View on the line 66 of Fig. 5.

Referring more particularly to the drawings l and 2 represent the separate ends of the rails to be connected each of which is provided with bolt apertures 3 adjacent their ends and both of which have the usual The chair. comprises separate members 6 and 7 each of which is lie between the head and base of the railsprovided with a vertical flange 8 adapted to and which isprovided with apertures 9 and slots 10. Extending outwardly from the flange 8 of the chair sections, are lJ-shaped flanges 11 which are adapted to receive the base of the railsandwhich are provided withdownwardly extending lugs lQ adaptcd to receive connectin bolts lfir Bridged b tween the vertical wigs and the Ushaped Fig. 3 is a detail perspective view flange atone end of each section 6 and. 7 is' a web 14 adapted to receive an adjusting bolt 15 the purpose of which will. behereinafter described. Slidahly mounted upon the 'U-shaped flanges and lying against the vertical flanges of the chair sections are adusting plates 16 having webs 17 formed at their ends to receive the ad usting bolt -'ihese plates provided with slots 18 which lie adjacent the apertures 9 in the vertical flange and with openings or holes 18 which with the apertures 10 in the vertical flanges. The apertures on. one plate are round while upon the op 'aosite plate they are square to receive th squared heads of connecting bolts 20 which pass through the apertures 1.9, the slots 10 and holes 3 in the rails and also through the siots 1.8 and holes 3 and 9. When the boits 20 are tightened up on the rails and the holts l5 operated to adjust the plates, it will be readily seen that the slots 18 permit the plates topass over the bolts and the bolts which extend throuoh the holes 3 and S hold the sections 5 and i of the chair stationary with the rail 1, whiie the .fiots l0 permit the bolts 20 which lit the holes and holes 3 to have movement relative to the sections 6 and 7. This causes the drawing of the section 2 toward the section 1. When the ends of the rails are brought together, a smooth tread surface is formed and bun'iping thereby eliminated. Thelugs 'lireinforce the, chair Sections and thereb Y prevent sagging of the ends of the rails uni". er pressure.-

Having thusdescribed the invention, what is claimed is 1. The combination with rail ends having bolt apertures therein, of a rail chair therefor comprising a pair of fish plate sections having apertures and slots therein, a pair of adjusting plates slidably mounted upon the fish plate sections, said adjusting plates having "slots registering with the apertures in the fish plate sections and apertures reg1stcring with the slots in the fish plate sections,

the apertures in the fish plate sectionsregistering with the apertures in one of the rails,
